AUTOGRAPHIC TELEGRAPH.

I SPECIFICATION forming part of Letters Patent No. 353.593, dated November 30, 1886.

Application filed June 30, 1886. Serial No. 206,692. No model.)

To all whom it may concern.-

Be it known that I, JAMES H. ROBERTSON, a citizen of the United States, and a resident of Rutherford, New Jersey, have invented a new and useful Improvement in Autographic Telegraphs, of which the following is a specification.

My invention relates to that class of'autographic telegraphs for which I have heretofore filed several applications for Letters Patent, designated with serial number as follows: Nos. 154,795, 177,435, and 200,412.

The object of this invention is to improve the several parts of such an apparatus so that it will operate with greater certainty, exactness, and promptness.

It consists in the several combinations of parts hereinafter described and claimed.

In the accompanying drawings, forming a part of this specification, Figure 1 represents a plan View of an apparatus embodying my invention. Fig. 2 is a side view of the same. Fig. 3 represents an end view. Fig. 4 is a view taken on a horizontal line immediately below the top of the table shown in Fig.1. Fig. 5 is a view in cross-section, taken on line 00 :t of Fig. 6, of a part of the receiving-instrument. Fig. 6 is a top view of the armatures andmagnetsofthereceiving-instrument. Fig. 7 1s a horizontal cross-section taken on line y 3 of Fig. 5, and Fig. 8 represents a vertical cross-section of a part of the sending orjransmitting instrument. Fig. 9 is a modification of the lever, in which it is formed with asocket at its top for a pencil or other holder. Fig. 10 is a view showing the switch mechanism and its connections, with a diagram of the circuits.

Referring to the transinitting-instrulnent, the reference-numbers 1 and 2 (see Figs. 4 and 8) represent the piles of carbon disks, as described in one of the previous applications hereinbefore referred to. For convenience, the two series of carbon disks are placed in receptacles formed in one piece of wood, 3. Each pile of disks is provided with a screwfollower, 4, for adjusting the normal pressure of the disks on each other.

The means I use for varying the pressure on the piles of carbon disks consists of a rod or 1 lever, 5, pivoted at its lower end in any suitable manner. In this instance the rod is provided at its lower end with an aperture, into which a pin or wire, 6, fits, the latter being secured to the base of the instrument. I preferably make the lever 5 long, so that the hand of the operator has alarge field of motion and is not cramped in its movement-s. On this rod or lever, opposite the piles of disks, I locate pressurepoints 7, of non-conducting material, and between said points and piles I arrange strips of metal, 8. to which the conductors are secured. I apply to the upper end of the lever, at about the surface of the table 9, a holder, 10, pivoted to said lever by a universal joint, 11. Instead of this arrangement, I can provide the upper end of the lever with a cavity, 11, of any form, into which a lead-pencil or other holder can be inserted for giving movement to the said lever. As the operator manipulates the holder, as in writingoutlining theletters-the pressure on the carbon disks is increased or diminished, with results as described in one of my applications hereinbeforc referred to. 7 The electro-magnets 12 and 13 of the receiver are arranged at right angles to each other, and at the point where the poles would meet, if extended, I locate a carrier-rod, 14, for carrying the armatures 15, 15, 16, and 16 of said magnets. (Thelatter,16, is not shown in the drawings.) The polesof said magnets are secured in position in the standards 17 by set-screws 18, and can be adjusted as may be required, each pole being adjustable independently of the other.

The armatures 15 and 16 for the two niagnets 12 and 13 are separated from each other by a non-magnetic block, 19, the obj cct of which is to prevent any influence being exercised by one magnet on the armature of the other, which would be the case were the two armatures formed in one piece or united by magnetic material-that is to say, if both magnets had one armature in common. The

armatures are united to the carrier-rod by setscrews 20, passing through the blocks 19. The armatures 15 and 16 are united to the armatures 15 and 16, respectively, by an iron rod or post, 21.

This connection ofthe two arma- 4o pen maybe used if it is placed at an angle so tures of opposite polarity completes the magnetic circuit, and of course gives an increase of power. ascrew-thread on its lower end, so that the parts connected can be adjusted nearer toor farther from each other. The carrierrod 14 is reduced in thickness at22, forming a spring, so that its armatures can easily and quickly respond to the varying attraction of the electro-magnets. The entire rod may be made of flexible material, if desired, or it may be pivoted; but in this case spiral or other springs will have to be used to keep the rod and armatures in their normal positions. To steady the movements of the carrier-rod,

, I secure to it an arm or extension, 23, which lightly on the paper.

dips into a liquid contained in a vessel, 24, adjustably mounted, through arm 27, on standard 25. This vessel has a depression, 26, in one side, extending a little beyond its center, so as to allow the carrier-rod 14 to occupy a centralposition in regard thereto, said rod carrying the extension 23, shaped, as shown, to

correspond somewhat with the .form of the.

vessel. This extension can be adjusted on the rod by means of the set-screw 27, so as to dip into the liquid more or less, as may be found necessary. The carrier-rod extends above the table 9 through an enlarged aperture, 28,'in the same, and is bifurcated at its upper end,

each bifurcation 29 being provided with a screw-bearing, 30, in which the pivot or shaft 31 of the counterweighted arm 32, carrying the receiving-pen 33, is mounted. The arm is weighted so that the pen shall bear only The said arm has a screw-threaded hole at its outer end,into which the receiving-pen is' screwed: The pen illustrated is a reservoir or fountain pen of the stylographic kind; but an ordinary fountainas to pass freely over the paper.

The reel of'paper used in the apparatus contained in the receptacle 31, and as the paper 37 uncoils it passes from said receptacle under the receiving pen or stylus and between the feed-rolls 35 and 36 ofthe paper-feed mechanism whereby it is fed forward. With the exception of the arresting rneans hereinafter described, I do not claim any novelty in the said feed mechanism, and it will not, therefore, be necessary to describe the same herein.

The switch-lever 38 is shown in the drawings in its normal position,with the bell 39 in circuit. The said switch-lever is provided with two contact-makers, 40 and 41, for the two circuits of the instruments, and these contact-makers in the normal position of the switch-lever connect with bindingposts 42 and 43, which are joined by wires 44. (See Fig. 4.) The circuit in this case is from battery 45 to binding-post 46, thence by conductor 47, springs 48 49, conductor 50, bell electro-magnets 51, and conductor 52 to ground. When the circuitis made and broken by the push-button 53, which acts to sepa- I have made the connection 21 with ground, andfrom battery 60, binding-post 61,

switch-lever, binding-post 55, conductors 62 63, receiver-magnet 1 3, and conductors 64 59 to ground.

If it is desired to put both receiver and transmitter in circuit, the switch-lever is shifted until its contact-makers are in connection with binding posts 65 66. The circuits in this case are as follows: from battery 45, switch-lever,

binding-post 65, conductors 67 68, pile of car- 9 bon disks 2, conductors 69 and 57,'magnet l2, and conductors 58 and 59 to ground, and from battery 60, binding-post 61, switch-lever, binding-post 66, conductors 70 71, pile of carbon disks 1, conductors 72 63, receiver-magnet 13, and conductors 64 59 to ground.

Whenever both transmitter and receiver or receiver only are put in circuit, the clock-work escapement is automatically released, and this is accomplished as follows: The switch-lever carries a roller or projection, 73, which, when the lever is thrown into its normal position,

rides over and depresses the outer end of brakelever 74,pivoted at 75, causing itsinner end to press firmly against the under side of ratchetwheel 76 of the clock-work mechanism, thus preventing any movement of the paper. As

the switch-lever is shifted to throw the receiver alone, or both receiver and transmitter, into circuit, the said projection of the switch-lever passes beyond the brake-lever, and the outer end of the latter is then thrown up by spring 77 leaving the clock-work mechanism free to move the paper.

It will be observed that the two circuits used are connected near the instruments and between thesame and ground to one and the same ground-wire, and ,this is done, of course, both at the transmitting and receiving station.

It will also be observed that the poles of the two batteries in the two circuits are opposed to each other, the purpose of which is to secure a more regular action.
